The parameters manufacturer, description and serial may be NULL or pointer to buffers to store the fetched strings.

Note

Use this function only in combination with ftdi_usb_find_all() as it closes the internal 'usb_dev' after use.

int ftdi_readstream (struct ftdi_context * ftdi, FTDIStreamCallback * callback, void * userdata, int packetsPerTransfer, int numTransfers)

Streaming reading of data from the device

Use asynchronous transfers in libusb-1.0 for high-performance streaming of data from a device interface back to the PC. This function continuously transfers data until either an error occurs or the callback returns a nonzero value. This function returns a libusb error code or the callback's return value.

For every contiguous block of received data, the callback will be invoked.

Parameters

ftdi pointer to ftdi_context
callback to user supplied function for one block of data
userdata
packetsPerTransfer number of packets per transfer
numTransfers Number of transfers per callback

int ftdi_poll_modem_status (struct ftdi_context * ftdi, unsigned short * status)

Poll modem status information

This function allows the retrieve the two status bytes of the device. The device sends these bytes also as a header for each read access where they are discarded by ftdi_read_data(). The chip generates the two stripped status bytes in the absence of data every 40 ms.

Layout of the first byte:

  • B0..B3 - must be 0
  • B4 Clear to send (CTS) 0 = inactive 1 = active
  • B5 Data set ready (DTS) 0 = inactive 1 = active
  • B6 Ring indicator (RI) 0 = inactive 1 = active
  • B7 Receive line signal detect (RLSD) 0 = inactive 1 = active

Layout of the second byte:

  • B0 Data ready (DR)
  • B1 Overrun error (OE)
  • B2 Parity error (PE)
  • B3 Framing error (FE)
  • B4 Break interrupt (BI)
  • B5 Transmitter holding register (THRE)
  • B6 Transmitter empty (TEMT)
  • B7 Error in RCVR FIFO
